A docket of all applications to the county clerk, whether such application shall be made for the purpose of being registered, or restored, or for the purpose of erasing a name on the register or for completing registration, shall be made out in the order of the precincts. The county clerk shall sit to hear such applications between the hours of 10:00 a.m. and 5:00 p.m. on Thursday, Friday and Saturday of the second week prior to the week in which the 1970 primary election for the nomination of candidates for State and county officers or any election thereafter is to be held. Witnesses may be sworn and examined upon the hearing of the applications.
Each person appearing in response to an application to have his name erased shall deliver to the county clerk a written affidavit, which shall be, in substance, in the words and figures following:
"I do solemnly swear that I am a citizen of the United States; that I do reside and have resided in the State of Illinois since the .... day of .... and in the county of .... in said state since the .... day of .... and in the .... precinct of the .... ward, in the city, village, incorporated town or town of .... in said county and state, since the .... day of .... and that I am .... years of age; and that I am the identical person registered in said precinct under the name I subscribe hereto."
This affidavit shall be signed and sworn to or affirmed before any person authorized to administer oaths or affirmations. The decision on each application shall be announced at once after the hearing, and a minute made thereof, and when an application to be registered or to be restored to the register or to complete registration shall be allowed, the county clerk shall cause a minute to be made upon the original and duplicate registration record cards.
All applications under this section and all hearings hereinafter provided may be heard by a deputy county clerk or clerks specially designated by the county clerk for this purpose, and a decision by a deputy so designated, shall become the decision of the county clerk upon approval by the county clerk.
In any case in which the county clerk refuses an application to be registered or restored or to have a registration completed, or orders a name erased or stricken from the register, application may be made to the circuit court to be placed upon the register, and such applications shall be heard, and appeals taken from refusal of such applications, in the manner provided in other civil actions. The court may, at its discretion, hear such applications upon the same days as are specified in this Section for hearings by the county clerk, and, in such cases, application to be heard by the court may be made on such days. Forms for applications to the court shall be furnished by the county clerk.
